EightyOne - RetroBIOS¶
Technical notes
Libretro port embeds zx81.rom and dkchr.rom as C arrays (xxd -i). Core never accesses filesystem for ROMs. Hardcodes MACHINEZX81. ref: 81-libretro/81/zx81/snap.c:487-508, src/libretro.cpp:393
Original EightyOne supports 15+ machines, loads ROMs from ROM/ directory. ref: EightyOne/Source/zx81/zx81.cpp:309, EightyOne/Source/HW_.cpp:2734
.info has no firmware declarations (firmware_count absent).
